perimeter of a table of dimensions 1 m by 3

m.

What is the distance traveled?

2) A window washer drops a brush from a scaf-

fold on a tall office building.

What is the speed of the falling brush after

2.7 s? (Neglect drag forces.) The acceleration

due to gravity is 9.8 m/s2 .

Answer in units of m/s

How far has it fallen in that time?

answer in units of m

3) With an average acceleration of −0.96 m/s2,

how long will it take a cyclist to bring a bicycle

with an initial speed of 14.8 m/s to a complete

stop?

Answer in units of s

4) A car traveling initially at +5.7 m/s acceler-

ates uniformly at the rate of +0.79 m/s2 for a

distance of 262 m.

What is its velocity at the end of the accel-

eration?

Answer in units of m/s

What is its velocity after it accelerates for 132

m?

Answer in units of m/s

What is its velocity after it accelerates for 65

m?

Answer in units of m/s

PLEASE give right answers + explain how you got it. Thanks!!
